Problems solved by technology

However, for each indoor unit, since there are differences in the optimal subcooling / superheating degree of the amount of refrigerant delivered to each indoor unit, it is not enough to measure the power consumption simply by using the running time of the above indoor units. precise
[0019] Therefore, the one-unit multi-terminal air conditioner of the prior art has the following problems, that is, it will cause inconvenience to the user because it cannot provide a method for accurately calculating the electricity bill.

Abstract

A method for calculating the electric consumption of each indoor unit in an air conditioner with multiple indoor units features that the overheat degree or overcold degree, the pressure of refrigerant and the capacity of each indoor unit are used as the basic parameters of calculation.

Description

technical field [0001] The present invention relates to a one-machine multi-terminal air conditioner, more precisely, relates to a method for calculating power consumption in multi-airconditioner (Method for calculating power consumption in multi-airconditioner), the above method is a method using several In the air conditioner of the indoor unit, the method of calculating the electricity bill used by each indoor unit separately. Background technique [0002] Generally, an air conditioner can perform cooling operation and heating operation according to user's needs. In the heating operation mode, the air conditioner can warm the room in cold winter by driving the heating cycle. In the desert mode, the air conditioner can cool the room in hot summer by driving the refrigeration cycle. In addition, the air conditioner can also adjust the humidity of the indoor air, so that the indoor air can be kept in a comfortable and clean state. [0003] Recently, products are being sou...
